Wire harness

ABSTRACT

A wire harness including: a wire; a tubular first outer cover accommodating the wire; a positioning member that is made of a synthetic resin and is attached to an end of the first outer cover; and a ring-shaped electromagnetic wave absorber that has a through hole through which the wire passes and is fixed to the positioning member, wherein the positioning member has a main body including an insertion portion inserted into the through hole, and a fitting portion that protrudes from an end of the main body and is fitted on the end of the first outer cover.

BACKGROUND

This disclosure relates to a wire harness.

Conventionally, wire harnesses, which are provided with wires that electrically connect a plurality of electrical devices and electromagnetic wave absorbing members that absorb electromagnetic waves (electromagnetic noise) emitted from the wires, are known as wire harnesses that are mounted in vehicles such as hybrid vehicles and electric vehicles. As a result of inserting a plurality of wires into a through hole in an electromagnetic wave absorbing member constituted by a ferrite core, the electromagnetic wave absorbing member is provided on an outer circumference of the wires in a wire harness of this type (see JP 2014-130886A, for example).

SUMMARY

Incidentally, with the above-described wire harness, the larger the electromagnetic waves to be reduced are, the larger the size of the electromagnetic wave absorbing member is. When a wire is inserted into such a large electromagnetic wave absorbing member, there is a risk that the electromagnetic wave absorbing member may vibrate due to vibration caused by traveling of the vehicle or the like, for example, and the wire may be shaken by the vibration of the electromagnetic wave absorbing member, and the wires may be damaged.

An exemplary aspect of the disclosure provides a wire harness capable of reducing damage to a wire.

The wire harness of the present disclosure includes: a wire; a tubular first outer cover accommodating the wire; a positioning member that is made of a synthetic resin and is attached to an end of the first outer cover; and a ring-shaped electromagnetic wave absorber that has a through hole through which the wire passes and is fixed to the positioning member, wherein the positioning member has a main body including an insertion portion inserted into the through hole, and a fitting portion that protrudes from an end of the main body and is fitted on the end of the first outer cover.

According to the wire harness of the present disclosure, an effect of being able to reduce damage to a wire is exhibited.

DETAILED DESCRIPTION OF EMBODIMENTS Description of Embodiments

First, embodiments of the present disclosure will be listed and described.

[1] The wire harness of the present disclosure includes: a wire; a tubular first outer cover member accommodating the wire; a positioning member that is made of a synthetic resin and is attached to an end portion of the first outer cover member; and a ring-shaped electromagnetic wave absorbing member that has a through hole through which the wire passes and is fixed to the positioning member, in which the positioning member has a main body portion including an insertion portion inserted into the through hole, and a fitting portion that protrudes from an end portion of the main body portion and is fitted on the end portion of the first outer cover member.

According to this configuration, the insertion portion of the positioning member is inserted inside the through hole of the electromagnetic wave absorbing member. As a result, a positioning member made of synthetic resin can be interposed between the inner circumferential surface of the through hole and the wire. For this reason, it is possible to suppress direct contact between the inner circumferential surface of the through hole and the outer circumferential surface of the wire. As a result, even if the electromagnetic wave absorbing member vibrates due to traveling of the vehicle or the like, it is possible to suppress damage to the wire caused by contact with the edge of the inner circumferential surface of the through hole.

Also, by adjusting the length of the main body portion between the insertion portion and the fitting portion, the positional relationship between the first outer cover member and the electromagnetic wave absorbing member can be easily set.

Here, a “ring” in the present specification includes a circular ring having a circular outer edge shape, a ring having an elliptical or ovoid outer edge shape, a polygonal ring having a polygonal outer edge shape, and a ring having a polygonal outer edge shape with rounded corners, and refers to a ring whose outer shape is composed of any closed shape connected by straight lines or curved lines. A “ring” includes a ring that is a shape having a through hole in a plan view, a shape in which the outer edge shape and the inner circumference shape of the through hole are the same shape, and a shape in which the outer edge shape and the inner circumference shape of the through hole are different from each other. A “ring” includes a ring having a predetermined length extending along the central axis direction in which the central axis passing through the center of the through hole extends, and the length thereof may be large or small. Also, a “ring” in the present specification may be regarded as a ring overall, and includes an object having a notch in a portion thereof, as with a C-shaped object.

[2] It is preferable that the positioning member has a first protruding portion that is provided between the insertion portion and the fitting portion and protrudes in a direction intersecting a length direction of the wire from an outer circumferential surface of the main body portion, and the first protruding portion opposes a first side surface of the electromagnetic wave absorbing member and opposes an end surface in an axial direction of the first outer cover member.

According to this configuration, for example, by bringing the first protruding portion into contact with the end surface of the first outer cover member, the positioning member can be easily positioned with respect to the first outer cover member. Also, by bringing the first side surface of the electromagnetic wave absorbing member into contact with the first protruding portion, the electromagnetic wave absorbing member can be easily positioned with respect to the positioning member. For this reason, the assembly workability of the wire harness can be improved.

Also, by bringing the first side surface of the electromagnetic wave absorbing member into contact with the first protruding portion, it is possible to restrict relative movement of the electromagnetic wave absorbing member with respect to the positioning member in the length direction of the wire. This makes it possible to suitably suppress positional misalignment of the electromagnetic wave absorbing member with respect to the positioning member. Furthermore, by bringing the first protruding portion into contact with the end surface of the first outer cover member, it is possible to restrict relative movement of the positioning member with respect to the first outer cover member in the length direction of the wire. This makes it possible to suitably suppress positional misalignment of the positioning member with respect to the first outer cover member.

[3] It is preferable that the first protruding portion is formed such that an amount of protrusion from the outer circumferential surface of the main body portion decreases from the insertion portion side toward the fitting portion side.

According to this configuration, the outer circumferential surface of the first protruding portion is formed in a tapered shape. For this reason, for example, even if a braided member or the like that is easily damaged is provided so as to surround the outer circumference of the first protruding portion, it is possible to suitably suppress damage to the braided member caused by contact with the outer circumferential surface of the first protruding portion.

[4] It is preferable that the first protruding portion is in contact with the first side surface of the electromagnetic wave absorbing member, and an outer circumferential surface of the first protruding portion at the portion in contact with the first side surface is formed so as to be flush with an outer circumferential surface of the electromagnetic wave absorbing member.

According to this configuration, the outer circumferential surface of the first protruding portion is formed flush with the outer circumferential surface of the electromagnetic wave absorbing member, and is formed in a tapered shape such that the amount of protrusion decreases from the portion formed flush with the outer circumferential surface as the distance from the electromagnetic wave absorbing member increases. For example, even if the corner portion of the electromagnetic wave absorbing member is formed at a pin angle, the outer circumferential surface of the first protruding portion formed continuously with the outer circumferential surface of the electromagnetic wave absorbing member is formed in a tapered shape, whereby the corner portion of the electromagnetic wave absorbing member can be formed in a pseudo-tapered shape by the first protruding portion. As a result, for example, even if a braided member or the like that is easily damaged is provided so as to surround the outer circumferences of the electromagnetic wave absorbing member and the first protruding portion, it is possible to suitably suppress damage to the braided member caused by contact with the outer circumferential surfaces of the electromagnetic wave absorbing member and the first protruding portion.

[5] It is preferable that the main body portion has a tubular shape through which the wire passes, the main body portion has a slit extending along an axial direction of the main body portion, the positioning member has a second protruding portion that protrudes in a direction intersecting the axial direction from an outer circumferential surface at an end portion on a side opposite to the fitting portion out of end portions in the axial direction of the main body portion, and the second protruding portion opposes a second side surface of the electromagnetic wave absorbing member.

According to this configuration, since the insertion portion is formed in a tubular shape, it is possible to more suitably suppress direct contact between the inner circumferential surface of the through hole and the outer circumferential surface of the wire. As a result, it is possible to suitably suppress damage to the wire caused by contact with the edge of the inner circumferential surface of the through hole.

Also, by bringing the side surface of the electromagnetic wave absorbing member into contact with the second protruding portion, the electromagnetic wave absorbing member can be easily positioned with respect to the positioning member. For this reason, the assembly workability of the wire harness can be improved. Furthermore, by bringing the second side surface of the electromagnetic wave absorbing member into contact with the second protruding portion, it is possible to restrict relative movement of the electromagnetic wave absorbing member with respect to the positioning member in the length direction of the wire. This makes it possible to suitably suppress positional misalignment of the electromagnetic wave absorbing member with respect to the positioning member.

[6] It is preferable that the second protruding portion is formed such that an amount of protrusion from the outer circumferential surface of the main body portion decreases as a distance from the electromagnetic wave absorbing member increases.

According to this configuration, the outer circumferential surface of the second protruding portion is formed in a tapered shape. For this reason, for example, even if a braided member or the like that is easily damaged is provided so as to surround the outer circumferential surface of the second protruding portion, it is possible to suitably suppress damage to the braided member caused by contact with the outer circumferential surface of the second protruding portion.

[7] It is preferable to further include a fixing member for fixing the positioning member to the wire, in which the positioning member has a fixing portion formed so as to protrude from the main body portion, and the fixing member is formed so as to fasten the wire and the fixing portion to each other.

According to this configuration, the positioning member is fixed to the wire by the fixing member, and the electromagnetic wave absorbing member is fixed to the positioning member. For this reason, it is possible to suppress positional misalignment of the positioning member with respect to the wire, and it is possible to suppress positional misalignment of the electromagnetic wave absorbing member with respect to the wire.

[8] It is preferable that the first outer cover member is a metal pipe, the fitting portion has a tubular shape through which the wire passes, and is fitted inside of the first outer cover member, and the fitting portion has a slit extending along the axial direction of the main body portion.

According to this configuration, the fitting portion of the positioning member is inserted inside the metal pipe. As a result, a positioning member made of synthetic resin can be interposed between the inner circumferential surface of the metal pipe and the wire. For this reason, it is possible to suppress direct contact between the inner circumferential surface of the pipe and the outer circumferential surface of the wire. As a result, it is possible to suppress damage to the wire caused by contact with the edge of the inner circumferential surface of the pipe.

[9] It is preferable to further include: a tubular electromagnetic shielding member that surrounds an outer circumference of the wire, the positioning member, and the electromagnetic wave absorbing member; and a restricting member that covers an outer circumferential surface of the electromagnetic shielding member, in which the restricting member is formed so as to fasten the electromagnetic shielding member toward the wire from an outer side of the electromagnetic shielding member.

According to this configuration, the electromagnetic waves emitted from the wire can be reduced by the electromagnetic wave absorbing member and the electromagnetic shielding member surrounding the outer circumference of the electromagnetic wave absorbing member. Also, since the electromagnetic shielding member is fastened toward the wire by the restricting member, it is possible to suppress the electromagnetic shielding member from expanding outward in the radial direction of the wire.

[10] It is preferable to further include: a connection member configured to fix an end portion in an axial direction of the electromagnetic shielding member in a state of being electrically connected to an outer circumferential surface of the first outer cover member; a second outer cover member that accommodates the wire and is formed spaced apart from the first outer cover member in the length direction of the wire; and a protective member that covers an outer circumference of the electromagnetic wave absorbing member and the positioning member and is formed so as to bridge between an outer circumference of the first outer cover member and an outer circumference of the second outer cover member, in which the protective member is formed so as to surround an outer circumference of the connection member.

According to this configuration, since the outer circumference of the electromagnetic wave absorbing member is covered by the protective member, the protective member can be interposed between the electromagnetic wave absorbing member and its peripheral components. Also, since the outer circumference of the connection member connecting the metal pipe and the electromagnetic shielding member is covered by the protective member, the protective member can be interposed between the connection member and its peripheral components. As a result, it is possible to suppress direct contact between the electromagnetic wave absorbing member and connection member and the peripheral components, and therefore it is possible to suppress damage to the electromagnetic wave absorbing member and the connection member caused by contact with the peripheral components.

DETAILED DESCRIPTION OF EMBODIMENT OF THE DISCLOSURE

A specific example of a wire harness according to this disclosure will be described with reference to the drawings below. In the drawings, some of the components may be exaggerated or simplified for the sake of description. Also, the dimensional proportions of some parts may differ from their actual proportions. “Parallel” and “orthogonal” in this specification include not only strictly parallel and orthogonal but also generally parallel and orthogonal in a range in which the effects of this embodiment are achieved. Note that the present disclosure is not limited to these examples, but is indicated by the claims, and all changes that fall within the meaning and range of equivalency of the claims are intended to be embraced therein.

Overall Configuration of Wire Harness 10

A wire harness 10 shown in FIG. 1 electrically connects two or three or more electric devices (devices). The wire harness 10 electrically connects, for example, an inverter 11 installed at the front of a vehicle V such as a hybrid vehicle or an electric vehicle, and a high-voltage battery 12 installed on the rear side of the vehicle V relative to the inverter 11. The wire harness 10 is routed, for example, so as to pass under a floor of the vehicle V or the like. For example, an intermediate portion of the wire harness 10 in the length direction is routed so as to pass outside the vehicle interior, such as under the floor of the vehicle V. The inverter 11 is connected to a wheel drive motor (not shown) that is a power source for vehicle travel. The inverter 11 generates AC power from the DC power of the high-voltage battery 12, and supplies the AC power to the motor. The high-voltage battery 12 is, for example, a battery capable of supplying a voltage of several hundred volts.

The wire harness 10 includes one or a plurality of (in the present embodiment, two) wires 20, a pair of connectors C1 that are attached to both end portions of the wire 20, an outer cover member 30 (cover) that collectively surrounds the plurality of wires 20, and an electromagnetic wave absorbing member 80 (electromagnetic wave absorber).

Configuration of Wire 20

One end portion of each wire 20 is connected to the inverter 11 via the connector C1, and the other end of each wire 20 is connected to the high-voltage battery 12 via the connector C1. Each wire 20 is formed in a long shape, for example, so as to extend in the front-rear direction of the vehicle V. Each wire 20 is formed, for example, so as to be bent in a two-dimensional shape or a three-dimensional shape depending on the arrangement path of the wire harness 10. Each wire 20 is, for example, a high-voltage wire capable of handling a high voltage and a large current. Each wire 20 may be, for example, a shielded wire having an electromagnetic shielding structure, or a non-shielded wire having no electromagnetic shielding structure. Each wire 20 of this embodiment is a non-shielded wire.

As shown in FIG. 2 , the wire 20 is a covered wire having a core wire 21 made of a conductor and an insulating covering 22 covering the outer circumference of the core wire 21.

Configuration of Core Wire 21

As the core wire 21, for example, a twisted wire obtained by twisting a plurality of metal stands together, a columnar conductor constituted by one columnar metal rod that is solid, or a tubular conductor that is hollow can be used. As the core wire 21, for example, a twisted wire, a columnar conductor, and a tubular conductor may be used in combination. Examples of the columnar conductor include a single core wire and a bus bar. The core wire 21 in this embodiment is a twisted wire. A metal material such as a copper-based metal material or an aluminum-based metal material can be used as the material of the core wire 21, for example.

The cross-sectional shape (i.e., a transverse cross-sectional shape) obtained by cutting the core wire 21 along a plane orthogonal to the length direction of the core wire 21 may be any shape. The transverse cross-sectional shape of each core wire 21 is a circular, semicircular, polygonal, square, or flat shape, for example. The transverse cross-sectional shape of the core wire 21 in this embodiment is a circular shape.

Configuration of Insulating Covering 22

The insulating coverings 22 respectively cover the outer circumferential surfaces of the core wires 21 over the entire circumference in the circumferential direction, for example. The insulating covering 22 is made of an insulating material such as a synthetic resin, for example. It is possible to use a synthetic resin containing polyolefin-based resin as a main component, such as crosslinked polyethylene or crosslinked polypropylene, as the material of the insulating covering 22, for example. Materials of one or more types can be used alone or in combination of two or more as the material of the insulating covering 22. The insulating covering 22 can be formed through, for example, extrusion molding (extrusion coating) performed on the core wire 21.

Configuration of Outer Cover Member 30

The outer cover member 30 has a long tubular shape overall. A plurality of wires 20 are accommodated in the internal space of the outer cover member 30. The outer cover member 30 is formed, for example, so as to surround the outer circumference of the plurality of wires 20 over the entire circumference in the circumferential direction. The outer cover member 30 protects the wire 20 from, for example, flying objects and water droplets. As the outer cover member 30, for example, a metal or resin pipe, a resin protector, a flexible corrugated tube made of resin or the like, a rubber waterproof cover, or a combination thereof can be used.

The outer cover member 30 has, for example, a metal pipe 40, a corrugated tube 50, and a protective member 60 (protective cover).

Configuration of Pipe 40

For example, the pipe 40 has a tubular shape that collectively surrounds the outer circumferences of the plurality of wires 20 overall. The pipe 40 is provided, for example, so as to surround the outer circumference of the plurality of wires 20 over the entire circumference in the circumferential direction. The pipe 40 is provided, for example, so as to surround a portion in the length direction (axial direction) of the wires 20. The outer circumferential surface of the pipe 40 is formed, for example, as a smooth surface. The pipe 40 of the present embodiment is formed in a cylindrical shape. As the material of the pipe 40, for example, a metal material such as a copper-based metal material or an aluminum-based metal material can be used. The pipe 40 has, for example, a function of collectively electromagnetically shielding the plurality of wires 20 and a function of protecting the plurality of wires 20 from flying objects and water droplets.

For example, a pair of attachment holes 41 are formed at the end portion of the pipe 40. Each attachment hole 41 is formed, for example, so as to pass through the pipe 40 in the radial direction of the pipe 40. Each attachment hole 41 is provided, for example, at a position spaced apart from an end surface 42 in the length direction (axial direction) of the pipe 40.

Configuration of Corrugated Tube 50

The corrugated tube 50 is provided, for example, spaced apart from the pipe 40 in the length direction of the wire 20. The corrugated tube 50 is provided, for example, between the pipe 40 and the connector C1. The end portion of the corrugated tube 50 is connected, for example, to the connector C 1. The corrugated tube 50 has, for example, a tubular shape that collectively surrounds the outer circumference of a plurality of wires 20 overall. The corrugated tube 50 is provided, for example, so as to surround the outer circumference of the plurality of wires 20 over the entire circumference in the circumferential direction. The corrugated tube 50 is provided, for example, so as to surround a portion in the length direction of the wires 20. The corrugated tube 50 has an accordion structure in which ring-shaped protrusions 51 and ring-shaped recesses 52 are arranged alternatingly along the length direction thereof. The corrugated tube 50 is more flexible than the core wire 21. The corrugated tube 50 of the present embodiment is formed in a cylindrical shape. Note that as the material of the corrugated tube 50, for example, a resin material having conductivity or a resin material having no conductivity can be used. As the resin material, for example, a synthetic resin such as polyolefin, polyamide, polyester, and ABS resin can be used.

Configuration of Protective Member 60

The protective member 60 is provided, for example, so as to bridge between the outer circumference of the pipe 40 and the outer circumference of the corrugated tube 50. The protective member 60 has, for example, a tubular shape in which both ends in the length direction of the wire 20 are open. As the material of the protective member 60, for example, an elastic material having a relatively high hardness can be used. As the elastic material, for example, rubber such as ethylene propylene diene rubber or elastomer can be used.

Configuration of Wire Harness 10

The wire harness 10 has, for example, a positioning member 90 provided on the outer circumference of the wires 20, an electromagnetic wave absorbing member 80 fixed to the positioning member 90, and a fixing member 100 fixing the positioning member 90 to the wires 20. The wire harness 10 has a braided member 110 that surrounds the wires 20, and restricting members 120 and 121 that cover the outer circumferential surface of the braided member 110.

Configuration of Electromagnetic Wave Absorbing Member 80

The electromagnetic wave absorbing member 80 is provided, for example, on the outer circumference of the wires 20 located between the pipe 40 and the corrugated tube 50. For example, in the length direction of the wire 20, the pipe 40 is provided on one side of the electromagnetic wave absorbing member 80, and the corrugated tube 50 is provided on the other side of the electromagnetic wave absorbing member 80. The electromagnetic wave absorbing member 80 is provided, for example, spaced apart from the pipe 40 in the length direction of the wire 20. The electromagnetic wave absorbing member 80 is provided, for example, spaced apart from the corrugated tube 50 in the length direction of the wire 20. The electromagnetic wave absorbing member 80 is exposed from, for example, the pipe 40 and the corrugated tube 50. The electromagnetic wave absorbing member 80 is provided, for example, so as to collectively surround the outer circumference of the plurality of wires 20. The electromagnetic wave absorbing member 80 absorbs some of the electromagnetic waves (electromagnetic noise) emitted from, for example, the plurality of wires 20.

The electromagnetic wave absorbing member 80 has, for example, a through hole 81 through which the plurality of wires 20 collectively pass. The electromagnetic wave absorbing member 80 has a ring shape, for example, due to having the through hole 81. The electromagnetic wave absorbing member 80 has, for example, a through hole 81 in a plan view from the length direction of the wire 20, and is formed in a ring shape having a predetermined length extending along the central axis direction in which the central axis passing through the center of the through hole 81 extends. In the present embodiment, the central axis direction of the electromagnetic wave absorbing member 80 is set to be a direction that extends parallel to the length direction of the wire 20. Note that in the following description, when the term “central axis direction” is simply used, it is assumed to mean the central axis direction of the electromagnetic wave absorbing member 80.

The through hole 81 is formed so as to pass through the electromagnetic wave absorbing member 80 in the length direction of the wire 20, for example. The plurality of wires 20 are provided so as to pass through the through hole 81, for example. The inner circumferential surface of the through hole 81 faces the outer circumferential surface of the wire 20.

The electromagnetic wave absorbing member 80 of the present embodiment is constituted by only a ring-shaped magnetic core 82. The magnetic core 82 of the present embodiment is formed in a circular ring shape. The magnetic core 82 has, for example, a function of reducing electromagnetic waves emitted from the wire 20 due to being arranged so as to oppose the wire 20 over the entire circumference in the circumferential direction of the wire 20. For example, the magnetic core 82 absorbs electromagnetic waves emitted from the wire 20 and converts the energy of the electromagnetic waves into mechanical energy such as vibration or thermal energy. As a result, the adverse effect of the electromagnetic waves emitted from the wire 20 on peripheral devices and the like is reduced.

The magnetic core 82 is, for example, a molded body containing a soft magnetic material. Examples of the soft magnetic material include iron (Fe), iron alloys and ferrites. Examples of the iron alloys include a Fe-silicon (Si) alloy and a Fe-nickel (Ni) alloy. As the magnetic core 82, for example, a ferrite core, an amorphous core, or a permalloy core can be used. The ferrite core is made of, for example, soft ferrite exhibiting soft magnetism. Examples of the soft ferrite include a ferrite containing nickel (Ni) and zinc (Zn) and a ferrite containing manganese (Mn) and zinc (Zn). The material of the magnetic core 82 can be appropriately selected, for example, according to the frequency band of the electromagnetic noise to be reduced.

As shown in FIG. 3 , the magnetic core 82 of the present embodiment is formed continuously over the entire circumference in the circumferential direction, and is formed in a closed ring shape. That is, the magnetic core 82 of the present embodiment is formed in a structure in which the entirety is connected to form a continuous ring, that is, an endless structure in which the start point and the end point coincide with each other. In other words, no slit that extends along the central axis direction of the electromagnetic wave absorbing member 80 is formed in the magnetic core 82 of the present embodiment. The magnetic core 82 of this embodiment is constituted by one component. Note that although the magnetic core 82 is constituted by one component in the present embodiment, a plurality of core materials may be combined to form a ring-shaped magnetic core 82. For example, the magnetic core 82 may be formed into a circular ring shape by combining a pair of core materials having semicircular transverse cross sections.

As shown in FIG. 2 , the magnetic core 82 has, for example, an outer circumferential surface 82A extending along the circumferential direction of the magnetic core 82, a side surface 82B that extends along the radial direction of the magnetic core 82 and faces the pipe 40 side, and a side surface 82C that extends along the radial direction of the magnetic core 82 and faces the corrugated tube 50 side. The side surfaces 82B and 82C are provided, for example, between the outer circumferential surface 82A and the inner circumferential surface of the through hole 81. The outer circumferential dimension of the magnetic core 82 is set to be larger than the inner circumferential dimension of the pipe 40 and the corrugated tube 50, for example.

The magnetic core 82 is provided, for example, on the outer circumferential surface of the positioning member 90. The magnetic core 82 is fitted, for example, to the outer circumference of the positioning member 90.

Configuration of Positioning Member 90

The positioning member 90 is provided on the outer circumference of the wire 20 located between the pipe 40 and the corrugated tube 50, for example. For example, in the length direction of the wires 20, the pipe 40 is provided on one side of the positioning member 90, and the corrugated tube 50 is provided on the other side of the positioning member 90. The positioning member 90 is provided, for example, spaced apart from the pipe 40 in the length direction of the wires 20. The positioning member 90 is provided, for example, spaced apart from the corrugated tube 50 in the length direction of the wires 20. The positioning member 90 is exposed from, for example, the pipe 40 and the corrugated tube 50. The positioning member 90 is fixed to, for example, the outer circumferential surface of the wires 20. The positioning member 90 is made of, for example, a synthetic resin. As the material of the positioning member 90, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used.

The positioning member 90 has, for example, a main body portion 90A (main body) including an insertion portion 91 inserted into the through hole 81 of the electromagnetic wave absorbing member 80, and a fitting portion 92 that protrudes from the end portion of the main body portion 90A and is fitted to the pipe 40. The positioning member 90 has a protruding portion 93 (first protrusion) that is provided between, for example, the insertion portion 91 and the fitting portion 92 and protrudes from the outer circumferential surface of the main body portion 90A in a direction intersecting the length direction of the wires 20, and a fixing portion 94 for fixing the positioning member 90 to the wires 20. The positioning member 90 has a protruding portion 95 (second protrusion) that is provided between, for example, the insertion portion 91 and the fixing portion 94 and protrudes from the outer circumferential surface of the main body portion 90A in a direction intersecting the length direction of the wire 20. The positioning member 90 is, for example, a single component in which the insertion portion 91, the fitting portion 92, the protruding portion 93, the fixing portion 94, and the protruding portion 95 are formed in one piece using a synthetic resin material.

Configuration of Main Body Portion 90A

The main body portion 90A is formed, for example, in a tubular shape through which the wires 20 pass. The main body portion 90A has, for example, a tubular shape that collectively surrounds the outer circumference of the plurality of wires 20 overall. The main body portion 90A of the present embodiment is formed in a cylindrical shape overall.

As shown in FIG. 4 , for example, a slit 91X extending along the axial direction of the main body portion 90A is formed in the main body portion 90A. The slit 91X is formed, for example, so as to extend over the entire length in the axial direction of the main body portion 90A. In the main body portion 90A of the present embodiment, the slit 91X is formed at one position in the circumferential direction of the main body portion 90A. Note that the main body portion 90A may have a plurality of slits 91X.

Configuration of Insertion Portion 91

As shown in FIG. 2 , the insertion portion 91 is formed, for example, at an intermediate portion in the axial direction of the main body portion 90A. The insertion portion 91 is fitted, for example, inside the through hole 81. The insertion portion 91 is interposed between the inner circumferential surface of the through hole 81 and the outer circumferential surface of the wires 20, for example. The insertion portion 91 has, for example, a tubular shape that collectively surrounds the outer circumference of the plurality of wires 20 overall. The insertion portion 91 is formed, for example, in a shape extending along the inner circumferential surface of the through hole 81. The insertion portion 91 of the present embodiment is formed in a cylindrical shape overall. The outer diameter of the insertion portion 91 is formed to be one size smaller than the inner diameter of the through hole 81, for example. The outer circumferential surface of the insertion portion 91 is in contact with, for example, the inner circumferential surface of the through hole 81. Note that the contact between the outer circumferential surface of the insertion portion 91 and the inner circumferential surface of the through hole 81 may be in the form of any of surface contact, line contact, and point contact. The inner circumferential surface of the insertion portion 91 opposes, for example, the outer circumferential surface of the wire 20. Due to having the slit 91X, for example, the insertion portion 91 is configured to be able to elastically deform so as to narrow the width of the slit 91X and reduce the diameter when inserted into the through hole 81.

Configuration of Fitting Portion 92

The fitting portion 92 is fitted, for example, inside the pipe 40. The fitting portion 92 is interposed between the inner circumferential surface of the pipe 40 and the outer circumferential surface of the wires 20, for example. The fitting portion 92 is formed, for example, in a tubular shape through which the wires 20 pass. The fitting portion 92 has, for example, a tubular shape that collectively surrounds the outer circumference of the plurality of wires 20 overall. The fitting portion 92 is formed in a shape extending along the inner circumferential surface of the pipe 40. The fitting portion 92 of the present embodiment is formed in a cylindrical shape overall. The outer diameter of the fitting portion 92 is formed to be one size smaller than the inner diameter of the pipe 40, for example.

As shown in FIG. 4 , for example, a slit 92X extending along the axial direction of the fitting portion 92 is formed in the fitting portion 92. The slit 92X is formed so as to extend, for example, over the entire length in the axial direction of the fitting portion 92. In the fitting portion 92 of the present embodiment, the slit 92X is formed at one location in the circumferential direction of the fitting portion 92. The slit 92X communicates with, for example, the slit 91X. The slit 92X is provided, for example, at a position at the same angle as the slit 91X in the circumferential direction of the fitting portion 92. That is, the slit 92X is provided at a position overlapping with the slit 91X in a plan view of the fitting portion 92 when viewed from the axial direction. By having the slit 92X, for example, the fitting portion 92 is configured to be able to elastically deform so as to narrow the width of the slit 92X and reduce the diameter when inserted into the pipe 40 (see FIG. 2 ). Note that the fitting portion 92 may have a plurality of slits 92X.

As shown in FIG. 2 , for example, a pair of projecting portions 96 are formed on the outer circumferential surface of the fitting portion 92. Each projecting portion 96 is formed so as to protrude outward in the radial direction of the fitting portion 92 from the outer circumferential surface of one end portion in the axial direction of the fitting portion 92, for example. Each projecting portion 96 is formed so as to protrude outward in the radial direction of the fitting portion 92 from the outer circumferential surface of the end portion on the side opposite to the protruding portion 93 out of the end portions in the axial direction of the fitting portion 92, for example. Each projecting portion 96 is locked, for example, to an attachment hole 41 of the pipe 40. The positioning member 90 is fixed to the end portion of the pipe 40 by locking the projecting portion 96 to the attachment hole 41.

Configuration of Protruding Portion 93

The protruding portion 93 is formed, for example, so as to protrude outward in the radial direction of the main body portion 90A from the outer circumferential surface of one end portion in the axial direction of the main body portion 90A. The protruding portion 93 is formed, for example, on the outer circumferential surface of the end portion on the side opposite to the fixing portion 94 out of the end portions in the axial direction of the main body portion 90A. The protruding portion 93 is formed, for example, over the entire length in the circumferential direction of the insertion portion 91. Note that the protruding portion 93 may also be formed on only a portion in the circumferential direction of the main body portion 90A.

The protruding portion 93 has a side surface 93A opposing the electromagnetic wave absorbing member 80, a side surface 93B opposing the pipe 40, and an outer circumferential surface 93C, which is a protruding leading end surface of the protruding portion 93.

The side surfaces 93A and 93B are formed, for example, so as to expand in the radial direction and the circumferential direction of the main body portion 90A. The side surface 93A is formed, for example, so as to oppose the side surface 82B of the electromagnetic wave absorbing member 80. The side surface 93A is in contact with, for example, the side surface 82B of the electromagnetic wave absorbing member 80. The thickness dimension along the radial direction of the side surface 93A is formed to be, for example, the same length as the thickness dimension along the radial direction of the side surface 82B. For this reason, the side surface 93A opposes, for example, the total length in the radial direction of the side surface 82B.

The side surface 93B is formed, for example, so as to oppose the end surface 42 in the axial direction of the pipe 40. The side surface 93B is in contact with, for example, the end surface 42 of the pipe 40. The thickness dimension along the radial direction of the side surface 93B is formed longer than, for example, the thickness dimension along the radial direction of the end surface 42.

The outer circumferential surface 93C is a surface located on the outer side in the radial direction of the outer surface of the protruding portion 93. The outer circumferential surface 93C is formed so as to extend in the axial direction and the circumferential direction of the main body portion 90A, for example. The outer circumferential surface 93C has, for example, an inclined surface 93D that is inclined so as to approach the outer circumferential surface of the main body portion 90A from the side surface 93A side toward the side surface 93B side. The protruding portion 93 is formed such that, for example, the amount of protrusion outward in the radial direction decreases as the distance from the electromagnetic wave absorbing member 80 increases. The inclined surface 93D is provided, for example, on at least a portion of the outer circumferential surface 93C of the protruding portion 93. Here, the portion of the outer circumferential surface 93C that is the closest to the side surface 82B of the electromagnetic wave absorbing member 80 is formed, for example, so as to be flush with the outer circumferential surface 82A of the electromagnetic wave absorbing member 80. That is, the outer circumferential surface 93C of the portion of the protruding portion 93 that comes into contact with the side surface 82B of the electromagnetic wave absorbing member 80 is formed so as to be flush with the outer circumferential surface 82A of the electromagnetic wave absorbing member 80.

Configuration of Fixing Portion 94

As shown in FIG. 4 , the fixing portion 94 is formed, for example, so as to extend along the axial direction of the main body portion 90A from the end surface in the axial direction of the main body portion 90A. The fixing portion 94 is formed so as to protrude in a direction away from the insertion portion 91. The fixing portion 94 is formed, for example, on only a portion in the circumferential direction of the main body portion 90A. The fixing portion 94 is formed, for example, at a position shifted from the slit 91X in the circumferential direction. The fixing portion 94 is formed, for example, at a position shifted by about π[rad] in the circumferential direction from the slit 91X.

The fixing portion 94 is formed in a thin plate shape, for example. The fixing portion 94 has an inner surface opposing the wires 20 (see FIG. 2 ) (here, a surface facing the upper side in the drawing) and an outer surface on the side opposite to the inner surface thereof. The inner and outer surfaces of the fixing portion 94 are formed, for example, in a curved surface shape. The inner and outer surfaces of the fixing portion 94 are formed, for example, on an arc surface coaxial with the main body portion 90A. The inner surface of the fixing portion 94 is, for example, formed continuously in one piece without a level difference with the inner circumferential surface of the insertion portion 91.

Configuration of Protruding Portion 95

The protruding portion 95 is formed, for example, so as to protrude outward in the radial direction of the main body portion 90A from the outer circumferential surface of the end portion in the axial direction of the main body portion 90A. The protruding portion 95 is formed, for example, on the outer circumferential surface of the end portion on the fixing portion 94 side of the end portions in the axial direction of the main body portion 90A. The protruding portion 95 is formed, for example, over the entire length in the circumferential direction of the main body portion 90A. Note that the protruding portion 95 may also be formed on only a portion in the circumferential direction of the main body portion 90A.

As shown in FIG. 2 , the protruding portion 95 has a side surface 95A opposing the electromagnetic wave absorbing member 80 and an outer circumferential surface 95B, which is a protrusion leading end surface of the protruding portion 95. The side surface 95A is formed so as to extend in the radial direction and the circumferential direction of the main body portion 90A, for example. The side surface 95A is formed so as to oppose the side surface 82C of the electromagnetic wave absorbing member 80, for example. The side surface 95A is in contact with, for example, the side surface 82C of the electromagnetic wave absorbing member 80. The thickness dimension along the radial direction of the side surface 95A is formed to be smaller than the thickness dimension along the radial direction of the side surface 82C, for example. For this reason, the side surface 95A opposes only a portion in the radial direction of the side surface 82C. The side surface 95A is formed, for example, so as to oppose the side surface 93A of the protruding portion 93. For example, the thickness dimension of the side surface 95A is formed smaller than the thickness dimension of the side surface 93A.

The outer circumferential surface 95B is a surface located on the outer side in the radial direction of the outer surface of the protruding portion 95. The outer circumferential surface 95B is formed so as to extend in the axial direction and the circumferential direction of the main body portion 90A, for example. The outer circumferential surface 95B has, for example, an inclined surface 95C that is inclined so as to approach the outer circumferential surface of the main body portion 90A from the insertion portion 91 side toward the fixing portion 94 side. That is, the outer circumferential surface 95B has an inclined surface 95C that is inclined so as to approach the outer circumferential surface of the main body portion 90A as the distance from the electromagnetic wave absorbing member 80 increases. In other words, the protruding portion 95 is formed such that the amount of protrusion outward in the radial direction decreases from the insertion portion 91 side to the fixing portion 94 side. The inclined surface 95C is provided, for example, on at least a portion of the outer circumferential surface 95B of the protruding portion 95.

For example, the positioning member 90 is attached to the end portion of the pipe 40 by inserting the fitting portion 92 inside the pipe 40 from the end surface 42 side with respect to the pipe 40. At this time, the fitting portion 92 is elastically deformed so as to narrow the width of the slit 92X and reduce the diameter. Then, when the fitting portion 92 is inserted into the pipe 40 to a position where the projecting portion 96 overlaps with the attachment hole 41 of the pipe 40 in the radial direction, the projecting portion 96 is fitted into the attachment hole 41. At this time, the fitting portion 92 is elastically restored so as to return to its original shape, that is, the fitting portion 92 is elastically restored such that the width of the slit 92X expands. Then, the projecting portion 96 comes into contact with the inner circumferential surface of the attachment hole 41, and the projecting portion 96 is locked to the attachment hole 41. As a result, the positioning member 90 is fixed to the end portion of the pipe 40.

The positioning member 90 is attached to the electromagnetic wave absorbing member 80 due to the insertion portion 91 being inserted into the through hole 81 of the electromagnetic wave absorbing member 80 from the side surface 82B side to the side surface 82C side, for example. At this time, the main body portion 90A including the insertion portion 91 is elastically deformed so as to narrow the width of the slit 91X and reduce the diameter. Then, when the protruding portion 95 at the end portion of the main body portion 90A passes through the through hole 81, the main body portion 90A elastically returns so as to return to its original shape, that is, elastically returns so that the width of the slit 91X widens. Then, the side surface 95A of the protruding portion 95 comes into contact with the side surface 82C of the electromagnetic wave absorbing member 80, and the protruding portion 95 is locked to the electromagnetic wave absorbing member 80. Furthermore, at this time, the side surface 93A of the protruding portion 93 comes into contact with the side surface 82B of the electromagnetic wave absorbing member 80, and the protruding portion 93 is locked to the electromagnetic wave absorbing member 80. As a result, a case is suppressed in which the positioning member 90 comes out of the through hole 81, and relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 is restricted in the length direction of the positioning member 90. In other words, the electromagnetic wave absorbing member 80 is fixed to the positioning member 90 by the protruding portions 93 and 95 provided on both sides of the electromagnetic wave absorbing member 80.

Configuration of Fixing Member 100

The fixing member 100 is provided, for example, so as to fix the positioning member 90 to the plurality of wires 20. The fixing member 100 is provided, for example, so as to fix the fixing portion 94 of the positioning member 90 to the plurality of wires 20. The fixing member 100 has, for example, a function of restricting the relative movement of the positioning member 90 with respect to the wires 20 in the length direction of the wires 20.

The fixing member 100 is formed, for example, by winding a tape member 101 around the fixing portion 94 and the wires 20. The tape member 101 has, for example, a pressure-sensitive adhesive layer on one surface. The tape member 101 is wound around the fixing portion 94 and the wires 20, for example, with the pressure-sensitive adhesive layer facing inward in the radial direction. The tape member 101 is wound around, for example, the outer surface of the fixing portion 94 and the outer circumferential surface of the wires 20.

Note that although not shown in the drawings, the tape member 101 has, for example, an overlap winding structure. Here, the overlap winding structure is a structure in which the tape member 101 is spirally wound such that predetermined portions in the width direction of the tape member 101 overlap each other. Note that the width direction of the tape member 101 is a direction extending along the length direction of the wire 20. As the overlap winding structure, for example, a half-wrap winding structure is preferable. Here, the half-wrap winding structure is a structure in which the tape member 101 is spirally wound so that portions that are approximately halfway in the width direction of the tape member 101 overlap each other.

The tape member 101 is formed so as to fasten, for example, the fixing portion 94 and the wires 20 to each other. The tape member 101 covers, for example, the outer surface of the fixing portion 94 and the outer circumferential surface of the plurality of wires 20 so as to fasten them in the direction in which the fixing portion 94 and the plurality of wires 20 approach each other. The tape member 101 is formed, for example, so as to fasten the fixing portion 94 and the wires 20 such that the inner surface of the fixing portion 94 and the outer circumferential surface of the wires 20 come into contact with each other.

The tape member 101 fixes the fixing portion 94 to the outer circumference of the wires 20, for example, such that the wires 20 are arranged offset to a portion in the circumferential direction of the insertion portion 91 inside the insertion portion 91. For example, the tape member 101 is wound around the outer circumferential surface of the fixing portion 94 and the wires 20 such that the wires 20 come into contact with the inner surface of the fixing portion 94 and are offset toward the fixing portion 94 side.

When the positioning member 90 is fixed to the wires 20 by the tape member 101, the electromagnetic wave absorbing member 80 fixed to the positioning member 90 is also fixed to the wires 20. As a result, the relative movement of the electromagnetic wave absorbing member 80 with respect to the wires 20 is restricted in the length direction of the wires 20, and therefore the electromagnetic wave absorbing member 80 can be prevented from being positionally misaligned.

Configuration of Braided Member 110

The braided member 110 has, for example, a tubular shape that collectively surrounds the outer circumference of the plurality of wires 20 overall. The braided member 110 is provided, for example, so as to surround the outer circumference of the wires 20 over substantially the entire length in the length direction of the wires 20. As the braided member 110, a braided member in which a plurality of metal strands are braided or a braided member in which a metal strand and a resin strand are braided in combination with each other can be used. As the material of the metal wire, for example, a metal material such as a copper-based metal material or an aluminum-based metal material can be used. As resin strands, for example, reinforcing fibers having excellent insulating properties and shear resistance such as para-aramid fibers can be used.

The braided member 110 is formed, for example, so as to collectively surround the outer circumference of the plurality of wires 20 in the internal space of the corrugated tube 50. In other words, the corrugated tube 50 is provided so as to surround the outer circumference of the wires 20 and the braided member 110. The braided member 110 is formed, for example, so as to surround the outer circumference of the electromagnetic wave absorbing member 80 and the positioning member 90 between the pipe 40 and the corrugated tube 50. The braided member 110 is formed, for example, such that the outer shape of the portion covering the electromagnetic wave absorbing member 80 and the positioning member 90 is larger than the outer shape of the other portions. The braided member 110 is provided, for example, in the internal space of the protective member 60 so as to surround the outer circumferences of the wires 20, the positioning member 90, the electromagnetic wave absorbing member 80, and the fixing member 100 over the entire circumference in the circumferential direction.

The braided member 110 is formed so as to cover the outer circumferential surface 82A of the magnetic core 82 and the outer circumferential surface 93C of the protruding portion 93 along the outer circumferential surfaces 82A and 93C, for example. The braided member 110 is formed so as to cover the inclined surface 93D of the protruding portion 93 and the outer circumferential surface of the pipe 40 along the inclined surface 93D and the outer circumferential surface at the end portion of the pipe 40, for example.

The end portion in the axial direction of the braided member 110 is, for example, electrically connected to the outer circumferential surface of the pipe 40.

The end portion in the axial direction of the braided member 110 is connected to the outer circumferential surface of the pipe 40 by a caulking ring 115 (connection) provided on the outer circumferential side of the braided member 110 in a state of being in direct contact with the outer circumferential surface of the pipe 40. The caulking ring 115 is fitted to the outside of the pipe 40, for example, in such a manner that the end portion of the braided member 110 is sandwiched between the caulking ring 115 and the outer circumferential surface of the pipe 40. Then, the caulking ring 115 is fastened inward in the radial direction of the pipe 40, whereby the end portion of the braided member 110 is fixed in direct contact with the outer circumferential surface of the pipe 40. As a result, the electrical continuity between the braided member 110 and the pipe 40 is stably ensured. The caulking ring 115 is provided, for example, on the outer circumferential surface of the pipe 40 between the end surface 42 of the pipe 40 and the attachment hole 41. The end portions of the braided member 110 are formed, for example, so as to be folded back toward the corrugated tube 50 side and outward in the radial direction. The folded-back braided member 110 is formed, for example, so as to surround the outer circumference of the caulking ring 115. Note that although not shown in the drawing, the end portion on the connector C1 side among the end portions in the axial direction of the braided member 110 is, for example, connected to ground (grounded) at the connector C1 or the like.

As the material of the caulking ring 115, for example, a copper-based, iron-based or aluminum-based metal material can be used. The material of the caulking ring 115 is preferably, for example, a metal material of the same type as the metal material constituting the pipe 40.

Configuration of Restricting Members 120 and 121

The restricting members 120 and 121 are formed so as to fasten the braided member 110, for example, from the outside of the braided member 110 toward the wires 20. The restricting members 120 and 121 are formed so as to fasten the braided member 110 inward in the radial direction, for example. The restricting members 120 and 121 have, for example, a function of restricting the braided member 110 from expanding outward in the radial direction of the wires 20. The restricting members 120 and 121 have, for example, a function of restricting the relative movement of the braided member 110 with respect to the electromagnetic wave absorbing member 80 in the length direction of the wires 20.

The restricting members 120 and 121 are formed, for example, by winding a tape member 122 around the outer circumferential surface of the braided member 110. The tape member 122 has, for example, a pressure-sensitive adhesive layer on one surface. The tape member 122 is wound around the braided member 110, for example, with the pressure-sensitive adhesive layer facing inward in the radial direction. Although not shown in the drawings, the tape member 122 has, for example, an overlap winding structure.

The restricting member 120 is provided, for example, on the outer circumferential surface of the braided member 110 located between the electromagnetic wave absorbing member 80 and the corrugated tube 50. The restricting member 120 is provided so as to overlap with the fixing portion 94, for example, in a direction intersecting the length direction of the wires 20. The restricting member 120 is provided so as to overlap with the fixing member 100, for example, in a direction intersecting the length direction of the wires 20.

The restricting member 121 is provided, for example, on the outer circumferential surface at the end portion in the axial direction of the braided member 110. The restricting member 121 is formed so as to cover, for example, the outer circumferential surface of the braided member 110 surrounding the outer circumferential surface 82A of the magnetic core 82. The restricting member 121 is formed so as to cover the outer circumferential surface of the braided member 110 that surrounds the outer circumferential surface 93C of the protruding portion 93, for example. The restricting member 121 is formed so as to cover the outer circumferential surface of the braided member 110 that surrounds the outer circumference of the caulking ring 115, for example. The restricting member 121 is formed so as to cover the outer circumferential surface of the pipe 40, for example. The restricting member 121 is continuously wound, for example, around a range from the outer circumferential surface of the pipe 40 exposed from the braided member 110 to the outer circumferential surface of the braided member 110 surrounding the outer circumferential surface 82A of the magnetic core 82.

Configuration of Protective Member 60

The protective member 60 is provided, for example, so as to surround the outer circumference of the electromagnetic wave absorbing member 80. The protective member 60 functions as, for example, a waterproof cover for waterproofing various members arranged inside of the protective member 60.

The protective member 60 includes, for example, a tubular connection tube portion 61 connected to the outer circumference of the pipe 40, a tubular connection tube portion 62 connected to the outer circumference of the corrugated tube 50, and a main body tube portion 63 that is provided between the connection tube portion 61 and the connection tube portion 62. The main body tube portion 63 is formed protruding outward in the radial direction relative to the outer circumference of the other portions, that is, the connection tube portions 61 and 62. The main body tube portion 63 is formed, for example, so as to protrude outward in the radial direction relative to the connection tube portions 61 and 62 over the entire circumference in the circumferential direction of the connection tube portions 61 and 62. The outer circumferential dimension of the main body tube portion 63 is formed to be larger than the outer circumferential dimension of the connection tube portions 61 and 62, for example. The protective member 60 is, for example, a single component formed in one piece by connecting the connection tube portion 61, the main body tube portion 63, and the connection tube portion 62. The connection tube portions 61 and 62 and the main body tube portion 63 of the present embodiment are formed continuously over the entire circumference in the circumferential direction, and are formed in an endless structure in which the start point and the end point coincide with each other. In other words, no slits extending along the length direction of the wires 20 are formed in the connection tube portions 61 and 62 and the main body tube portion 63 of the present embodiment.

In the protective member 60, for example, the connection tube portion 61 is fitted to the outer circumference of the pipe 40, and the connection tube portion 62 is fitted to the outer circumference of the corrugated tube 50.

The connection tube portion 61 is formed in a tubular shape having a size that can be fitted to the outer circumference of the pipe 40, for example. The connection tube portion 61 of the present embodiment is formed in a cylindrical shape. On the inner circumferential surface of the end portion of the connection tube portion 61, for example, one or a plurality (here, three) lips 61A are formed so as to protrude toward the outer circumferential surface of the pipe 40. Each lip 61A is continuously formed, for example, over the entire circumference in the circumferential direction of the inner circumferential surface of the connection tube portion 61, and is formed in an endless structure. Each lip 61A is formed, for example, so as to be in close contact with the outer circumferential surface of the pipe 40 when the connection tube portion 61 is fitted to the outer circumferential surface of the pipe 40.

For example, a coupling member 65 is provided on the outer circumferential surface of the connection tube portion 61. As the coupling member 65, for example, a cable tie made of resin or metal, a caulking ring, a tape member, or the like can be used. The connection tube portion 61 is fastened from the outer circumferential side by the coupling member 65 and fixed to the pipe 40. For example, the connection tube portion 61 is fastened from the outer circumferential side by the coupling member 65 until it is in close contact with the pipe 40 in a liquid-tight manner. As a result, it is possible to suppress a case in which water enters the inside of the protective member 60 from between the connection tube portion 61 and the pipe 40.

The connection tube portion 62 is formed in, for example, a tubular shape having a size that can be fitted to the outer circumference of the corrugated tube 50. The connection tube portion 62 of the present embodiment is formed in a cylindrical shape. On the inner circumferential surface of the end of the connection tube portion 62, for example, one or more (here, three) lips 62A that engage with the corrugated tube 50 are formed. Each lip 62A is formed continuously over the entire circumference in the circumferential direction of the inner circumferential surface of the connection tube portion 62, for example, and is formed in an endless structure. Each lip 62A is formed, for example, so as to enter a ring-shaped recess 52 of the corrugated tube 50 when the connection tube portion 62 is fitted to the outer circumference of the corrugated tube 50.

For example, a coupling member 66 is provided on the outer circumferential surface of the connection tube portion 62. As the coupling member 66, for example, a cable tie made of resin or metal, a caulking ring, a tape member, or the like can be used. The connection tube portion 62 is fastened from the outer circumferential side by the coupling member 66 and is fixed to the corrugated tube 50. For example, the connection tube portion 62 is fastened from the outer circumferential side by the coupling member 66 until it is in close contact with the corrugated tube 50 in a liquid-tight manner. As a result, it is possible to suppress a case in which water enters the inside of the protective member 60 from between the connection tube portion 62 and the corrugated tube

For example, one end portion of the main body tube portion 63 is formed continuously in one piece with the connection tube portion 61, and the other end is formed continuously in one piece with the connection tube portion 62. The main body tube portion 63 is formed in a tubular shape having a size capable of accommodating, for example, the electromagnetic wave absorbing member 80. The main body tube portion 63 of the present embodiment is formed in a cylindrical shape. The main body tube portion 63 is formed so as to surround the electromagnetic wave absorbing member 80 over the entire circumference in the circumferential direction. The main body tube portion 63 is provided, for example, so as to surround the wires 20, the positioning member 90, the electromagnetic wave absorbing member 80, the fixing member 100, the braided member 110, and the restricting members 120 and 121, which are exposed from the pipe 40 and the corrugated tube 50, over the entire circumference in the circumferential direction. The main body tube portion 63 is provided, for example, so as to surround the outer circumference of the caulking ring 115 over the entire circumference in the circumferential direction.

Next, the actions and effects of this embodiment will be described.

(1) The wire harness 10 has the wires 20, the pipe 40 accommodating the wires 20, the positioning member 90 made of synthetic resin attached to the end portion of the pipe 40, and has the ring-shaped electromagnetic wave absorbing member 80 that has the through hole 81 through which the wires 20 pass and is fixed to the positioning member 90. The positioning member 90 has the main body portion 90A including the insertion portion 91 inserted into the through hole 81, and the fitting portion 92 that protrudes from the end portion of the main body portion 90A and is fitted to the end portion of the pipe 40.

According to this configuration, the insertion portion 91 of the positioning member 90 is inserted inside the through hole 81 of the electromagnetic wave absorbing member 80. As a result, the positioning member 90 made of a synthetic resin can be interposed between the inner circumferential surface of the through hole 81 and the wires 20. For this reason, it is possible to suppress direct contact between the inner circumferential surface of the through hole 81 and the outer circumferential surface of the wires 20. As a result, even if the electromagnetic wave absorbing member 80 vibrates due to the traveling of the vehicle or the like, it is possible to suppress damage to the wire 20 caused by contact with the edge of the inner circumferential surface of the through hole 81.

(2) Also, by adjusting the length of the main body portion 90A between the insertion portion 91 and the fitting portion 92, the positional relationship between the pipe 40 and the electromagnetic wave absorbing member 80 can be easily set. That is, by adjusting the length of the main body portion 90A between the insertion portion 91 and the fitting portion 92, the separation distance of the electromagnetic wave absorbing member 80 with respect to the pipe 40 can be easily set.

(3) The fitting portion 92 is fitted inside the metal pipe 40. As a result, the positioning member 90 made of synthetic resin can be interposed between the inner circumferential surface of the metal pipe 40 and the wire 20. For this reason, it is possible to suppress direct contact between the inner circumferential surface of the pipe 40 and the outer circumferential surface of the wires 20. As a result, it is possible to suppress damage to the wires 20 caused by contact with the edge of the inner circumferential surface of the pipe 40.

(4) In the positioning member 90, the insertion portion 91 and the fitting portion 92 are formed in one piece. For this reason, it is possible to reduce the number of components compared to the case where the member that protects the wires 20 from the edge of the inner circumferential surface of the through hole 81 of the electromagnetic wave absorbing member 80 and the member that protects the wires 20 from the edge of the inner circumferential surface of the pipe 40 are provided separate from each other.

(5) The electromagnetic wave absorbing member 80 is fixed to the metal pipe 40 via the positioning member 90. For this reason, the electromagnetic wave absorbing member 80 can be stably held by the highly-rigid pipe 40. As a result, it is possible to suppress vibration of the electromagnetic wave absorbing member 80 caused by vibration accompanying the traveling of the vehicle or the like, and it is possible to suppress damage to the wires 20 caused by vibration of the electromagnetic wave absorbing member 80.

(6) The positioning member 90 is provided with the protruding portion 93, which is provided between the insertion portion 91 and the fitting portion 92 and protrudes in a direction intersecting the length direction of the wires 20 from the outer circumferential surface of the main body portion 90A. By bringing the protruding portion 93 into contact with the end surface 42 of the pipe 40, the positioning member 90 can be easily positioned with respect to the pipe 40. Also, by bringing the side surface 82B of the electromagnetic wave absorbing member 80 into contact with the protruding portion 93, the electromagnetic wave absorbing member 80 can be easily positioned with respect to the positioning member 90. For this reason, the assembly workability of the wire harness 10 can be improved.

(7) Also, by bringing the side surface 82B of the electromagnetic wave absorbing member 80 into contact with the protruding portion 93, relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 in the length direction of the wire 20 can be restricted. As a result, the positional misalignment of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 can be suitably suppressed. Furthermore, by bringing the end surface 42 of the pipe 40 into contact with the protruding portion 93, relative movement of the positioning member 90 with respect to the pipe 40 in the length direction of the wire 20 can be restricted. As a result, positional misalignment of the positioning member 90 with respect to the pipe 40 can be suitably suppressed.

(8) The protruding portion 93 was formed such that the amount of protrusion from the outer circumferential surface of the main body portion 90A decreases from the insertion portion 91 side toward the fitting portion 92 side. Also, the outer circumferential surface 93C of the protruding portion 93 at the portion in contact with the side surface 82B of the electromagnetic wave absorbing member 80 was formed so as to be flush with the outer circumferential surface 82A of the electromagnetic wave absorbing member 80. According to this configuration, the outer circumferential surface 93C of the protruding portion 93 is formed flush with the outer circumferential surface 82A of the electromagnetic wave absorbing member 80, and is formed in a tapered shaped such that the amount of protrusion decreases from the portion formed flush with the outer circumferential surface 82A as the distance from the electromagnetic wave absorbing member 80 increases. For example, even if the corner portion of the electromagnetic wave absorbing member 80 is formed at a pin angle, the outer circumferential surface 93C of the protruding portion 93 formed continuously with the outer circumferential surface of the electromagnetic wave absorbing member 80 is formed in a tapered shape, whereby the corner portion of the electromagnetic wave absorbing member 80 can be formed in a pseudo-tapered shape. As a result, even if the braided member 110 is provided so as to surround the electromagnetic wave absorbing member 80 and the outer circumference of the protruding portion 93, it is possible to suitably suppress damage to the braided member 110 caused by contact with the outer circumferential surface 82A of the electromagnetic wave absorbing member 80 and the outer circumferential surface 93C of the protruding portion 93.

(9) Furthermore, the outer circumferential surface 93C of the protruding portion 93 is formed on the inclined surface 93D that is inclined so as to approach the outer circumferential surface of the pipe 40 as the fitting portion 92 is approached. For this reason, it is possible to reduce a level difference between the outer circumferential surface 93C of the protruding portion 93 and the outer circumferential surface of the pipe 40. As a result, the restricting member 121 (tape member 122) can be suitably wound around the braided member 110 that covers the outer circumferential surface 93C of the protruding portion 93 and the outer circumferential surface of the pipe 40.

(10) The positioning member 90 is provided with the protruding portion 95 protruding in a direction intersecting the axial direction from the outer circumferential surface of the end portion on the side opposite to the fitting portion 92 of the end portions in the axial direction of the main body portion 90A. By bringing the side surface 82C of the electromagnetic wave absorbing member 80 into contact with the protruding portion 95, the electromagnetic wave absorbing member 80 can be easily positioned with respect to the positioning member 90. For this reason, the assembly workability of the wire harness 10 can be improved.

(11) Also, by bringing the side surface 82C of the electromagnetic wave absorbing member 80 into contact with the protruding portion 95, it is possible to restrict relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 in the length direction of the wires 20. As a result, positional misalignment of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 can be suitably suppressed.

(12) The electromagnetic wave absorbing member 80 is fixed to the positioning member 90 by the protruding portions 93 and 95 of the positioning member 90. According to this configuration, it is not necessary to provide a member for fixing the electromagnetic wave absorbing member 80 to the positioning member 90 separately from the positioning member 90, and therefore the number of components can be reduced.

(13) The restricting members 120 and 121 were formed such that the braided member 110 was fastened from the outside of the braided member 110 toward the wires 20. For this reason, it is possible to suitably suppress the braided member 110 from expanding outward in the radial direction of the wires 20. As a result, the workability when attaching the protective member 60 so as to cover the outer circumference of the braided member 110 can be improved.

(14) The electromagnetic wave absorbing member 80 and the protective member 60 covering the outer circumference of the caulking ring 115 were provided. As a result, the protective member 60 can be interposed between the electromagnetic wave absorbing member 80 and its peripheral components, and the protective member 60 can be interposed between the caulking ring 115 and its peripheral components. For this reason, since it is possible to suppress direct contact between the electromagnetic wave absorbing member 80 and caulking ring and the peripheral components, it is possible to suppress damage to the electromagnetic wave absorbing member 80 and the caulking ring 115 caused by contact with the peripheral components.

Other Embodiments

The above-described embodiment can be implemented with the following modifications. The above-described embodiment and the following modified examples can be implemented in combination with each other as long as there is no technical contradiction.

-   -   The installation positions of the restricting members 120 and         121 of the above-described embodiment are not particularly         limited.

For example, as shown in FIG. 5 , the restricting member 120 may also be provided between the fixing portion 94 and the corrugated tube 50. That is, the restricting member 120 may also be provided at a position that does not overlap with the fixing portion 94 in the direction intersecting the length direction of the wire 20.

-   -   In the above-described embodiment, the restricting members 120         and 121 are constituted by the tape member 122, but there is no         limitation to this. For example, a metal band or a resin cable         tie may be used as the restricting members 120 and 121.     -   The restricting member 121 of the above-described embodiment may         be omitted.     -   The restricting member 120 of the above-described embodiment may         be omitted.     -   In the above-described embodiment, the fixing member 100 was         constituted by the tape member 101, but there is no limitation         to this. For example, a metal band or a resin cable tie may be         used as the fixing member 100.     -   In the positioning member 90 of the above-described embodiment,         the outer circumferential surface 93C of the portion of the         protruding portion 93 that is in contact with the side surface         82B of the electromagnetic wave absorbing member 80 was formed         so as to be flush with the outer circumferential surface 82A of         the electromagnetic wave absorbing member 80, but there is no         limitation to this.

For example, as shown in FIG. 6 , the thickness dimension of the side surface 93A of the protruding portion 93 may be formed smaller than the thickness dimension of the side surface 82B of the electromagnetic wave absorbing member 80. In this case, the side surface 93A opposes only a portion in the radial direction of the side surface 82B.

In the positioning member 90 of the above-described embodiment, the protruding portion 93 was formed such that the protruding amount in the radial direction from the outer circumferential surface of the main body portion 90A decreases as the distance from the electromagnetic wave absorbing member 80 increases. However, the shape of the protruding portion 93 is not limited to this.

For example, as shown in FIG. 7 , the protruding portion 93 may be formed such that the amount of protrusion of the protruding portion 93 is the same over the entire length of the protruding portion 93 in the axial direction of the main body portion 90A. That is, the formation of the inclined surface 93D of the protruding portion 93 may be omitted.

-   -   The protruding portion 93 may be omitted from the positioning         member 90 of the above-described embodiment.     -   In the positioning member 90 of the above-described embodiment,         the protruding portion 95 was formed such that the amount of         protrusion outward in the radial direction from the outer         circumferential surface of the main body portion 90A decreases         from the insertion portion 91 side toward the fixing portion 94.         However, the shape of the protruding portion 95 is not limited         to this.

For example, as shown in FIG. 7 , the protruding portion 95 may be formed such that the amount of protrusion of the protruding portion 95 is the same over the entire length of the protruding portion 95 in the axial direction of the main body portion 90A. That is, the formation of the inclined surface 95C of the protruding portion 95 may be omitted.

-   -   The protruding portion 95 may be omitted from the positioning         member 90 of the above-described embodiment.     -   The position of the fixing portion 94 in the positioning member         90 of the above-described embodiment is not particularly         limited. For example, the fixing portion 94 may be provided         between the insertion portion 91 and the protruding portion 93.     -   A plurality of fixing portions 94 may be provided on the         positioning member 90 of the above-described embodiment.     -   For example, as shown in FIG. 8 , the fixing portion 94 may be         omitted from the positioning member 90.     -   In the positioning member 90 of the above-described embodiment,         the main body portion 90A was formed in a tubular shape, but the         present disclosure is not limited to this. For example, the         transverse cross-sectional shape of the main body portion 90A         may be formed in a semicircular shape.     -   In the positioning member 90 of the above-described embodiment,         the fitting portion 92 was fitted inside the pipe 40, but there         is no limitation to this. For example, the fitting portion 92         may be fitted to the outside of the pipe 40.     -   In the positioning member 90 of the above-described embodiment,         the fitting portion 92 was formed in a tubular shape, but there         is no limitation to this. For example, the transverse         cross-sectional shape of the fitting portion 92 may be formed in         a semicircular arc shape.     -   In the above-described embodiment, the electromagnetic wave         absorbing member 80 was fixed to the positioning member 90 by         the protruding portions 93 and 95 of the positioning member 90,         but the method of fixing the electromagnetic wave absorbing         member 80 to the positioning member 90 is not particularly         limited. For example, the electromagnetic wave absorbing member         80 may be fixed to the positioning member 90 by fastening the         electromagnetic wave absorbing member 80 toward the positioning         member 90 with a tape member or the like.     -   In the above-described embodiment, the protective member 60 was         embodied in an endless structure, but there is no limitation to         this. That is, in the above-described embodiment, the protective         member 60 was embodied as already being formed as a cylinder in         the state before the electromagnetic wave absorbing member 80 is         arranged inside, but there is no limitation to this.

For example, as shown in FIG. 9 , the protective member 60 may also be embodied in a sheet-like structure having a slit 67 extending along the length direction of the wire 20. The protective member 60 of this modified example is formed, for example, so as to have a tubular shape by winding a flexible sheet in the circumferential direction of the wires 20. The protective member 60 has, for example, an end portion 68 in a first direction (in FIG. 9 , the circumferential direction of the wires 20) intersecting the length direction of the wires 20, and an end portion 69 on a side opposite to the end portion 68 in the first direction. The protective member 60 is formed so as to have a tubular shape, for example, by overlapping the end portion 68 and the end portion 69 in the radial direction of the electromagnetic wave absorbing member 80. The inner circumferential dimension of the protective member 60 can be adjusted to match the outer circumferential dimension of the electromagnetic wave absorbing member 80 by, for example, adjusting the overlapping width between the end portion 68 and the end portion 69. The protective member 60 has elasticity according to which, for example, it is possible to return from a tubular state capable of surrounding the outer circumference of the electromagnetic wave absorbing member 80 to a sheet state of not surrounding the outer circumference of the electromagnetic wave absorbing member 80.

The protective member 60 is fixed to the outer circumferences of the pipe 40 and the corrugated tube 50 by, for example, the coupling members 65 and 66 shown in FIG. 2 , whereby the tubular state is maintained. As the coupling members 65 and 66, for example, a tape member, a cable tie, a caulking ring, or the like can be used.

Next, a configuration used when tape members 65A and 66A are respectively used as the coupling members 65 and 66 will be described with reference to FIG. 10 .

The tape member 65A is formed, for example, so as to fix the end portion in the length direction of the protective member 60 to the outer circumferential surface of the pipe 40. The tape member 66A is formed, for example, so as to fix the end portion in the length direction of the protective member 60 to the outer circumferential surface of the corrugated tube 50.

The tape member 65A is wound, for example, over the outer circumferential surface of the end portion in the length direction of the protective member 60 and the outer circumferential surface of the pipe 40 exposed from the protective member 60. The tape member 65A is continuously wound around the range from the outer circumferential surface of the protective member 60 to the outer circumferential surface of the pipe 40, for example. The tape member 65A has, for example, an overlap winding structure. The tape member 65A is wound around the outer circumference of the end portion of the protective member 60 such that, for example, the tubular state of the protective member 60 is maintained.

The tape member 66A is wound, for example, over the outer circumferential surface of the end portion in the length direction of the protective member 60 and the outer circumferential surface of the corrugated tube 50 exposed from the protective member 60. The tape member 66A is continuously wound around the range from the outer circumferential surface of the protective member 60 to the outer circumferential surface of the corrugated tube 50. The tape member 66A has, for example, an overlap winding structure. The tape member 66A is wound around the outer circumference of the end portion of the protective member 60 such that, for example, the tubular state of the protective member 60 is maintained.

-   -   An adhesive layer or a pressure-sensitive adhesive layer may be         provided on one surface of the protective member 60 shown in         FIG. 9 . For example, an adhesive layer or a pressure-sensitive         adhesive layer may be provided on one surface of the end portion         69 of the protective member 60. According to this configuration,         if the end portion 69 is overlaid on the end portion 68 of the         protective member 60, the end portion 69 can be adhered to the         end portion 68 by an adhesive layer or a pressure-sensitive         adhesive layer. As a result, it is possible to suitably suppress         a case in which the protective member 60 returns to the sheet         state at a stage prior to being fixed by the tape members 65A         and 66A (see FIG. 10 ).     -   As the material of the protective member 60 of the         above-described embodiment, for example, a material having more         excellent impact resistance and a more excellent cushioning         property than the pipe 40 and the corrugated tube 50 can be         used. For example, as the material of the protective member 60,         for example, a material having better sound absorption than the         pipe 40 and the corrugated tube 50 can be used. As the material         of such a protective member 60, for example, a porous material         can be used. As the material of the protective member 60, for         example, a foamed resin can be used. The bubble structure in the         foamed resin may be an open cell structure or a closed cell         structure. As the material of the protective member 60, for         example, urethane foam, polyethylene foam,         ethylene-propylene-diene rubber foam, or the like can be used.         By using the material described above as the material of the         protective member 60, the protective member 60 can be suitably         used as a cushioning member.

According to this configuration, the protective member 60 serving as a cushioning member can be interposed between the electromagnetic wave absorbing member 80 and its peripheral components. As a result, it is possible to suppress the generation of abnormal noise caused by contact between the electromagnetic wave absorbing member 80 and the peripheral components.

-   -   In the above-described embodiment, the caulking ring 115 was         used as the connecting member for fixing the end portion of the         braided member 110 in a state of being electrically connected to         the outer circumferential surface of the pipe 40, but there is         no limitation to this. For example, instead of the caulking ring         115, a metal band, a resin cable tie, a tape member, or the like         may be used as the connecting member.     -   In the above-described embodiment, the metal pipe 40 was         embodied as the first outer cover member (first outer cover),         and the corrugated tube 50 was embodied as the second outer         cover member (second outer cover), but the present disclosure is         not limited thereto. For example, as the first outer cover         member, a hard resin pipe, a corrugated tube, or a rubber         waterproof cover can be used. Also, as the second outer cover         member, for example, a hard resin pipe, a metal pipe, or a         rubber waterproof cover can be used. For example, the first         outer cover member and the second outer cover member may be         embodied in outer cover members of the same type.     -   In the above-described embodiment, the braided member 110 was         provided so as to cover the outer circumference of the         electromagnetic wave absorbing member 80, but there is no         limitation to this. For example, the braided member 110 may be         passed through the through hole 81 of the electromagnetic wave         absorbing member 80. In this case, the braided member 110 is         passed through the through hole 81 while surrounding the outer         circumference of the plurality of wires 20, for example.     -   Instead of the braided member 110 of the above-described         embodiment, another electromagnetic shielding member         (electromagnetic shield) such as metal foil may be used.     -   The braided member 110 in the above-described embodiment may         also be omitted.     -   The wires 20 of the above-described embodiment may also be         changed to shielded wires.     -   In the above-described embodiment, the electromagnetic wave         absorbing member 80 was constituted by only the magnetic cores         82, but there is no limitation to this. For example, the         electromagnetic wave absorbing member 80 may also be configured         to include a magnetic core 82 and a case for accommodating the         magnetic core 82.     -   There is no particular limitation to the number and installation         position of the electromagnetic wave absorbing member 80 in the         above-described embodiment. For example, two or more         electromagnetic wave absorbing members 80 may be provided for         the wire harness 10.     -   In the above-described embodiment, there were two wires 20         accommodated inside of the outer cover member 30, but the number         of wires 20 is not particularly limited, and the number of wires         20 can be changed according to the specification of the         vehicle V. For example, the number of wires 20 accommodated         inside the outer cover member 30 may be one or three or more.         For example, it is possible to use a configuration in which a         low-voltage wire connecting a low-voltage battery and various         low-voltage devices (e.g., a lamp, car audio, etc.) is added as         a wire accommodated in the outer cover member 30.     -   The arrangement relationship between the inverter 11 and the         high-voltage battery 12 in the vehicle V is not limited to the         above-described embodiment, and may be appropriately changed         according to the vehicle configuration.

For example, as shown in FIG. 11 , the high-voltage battery 12 may be arranged on approximately the entirety of the floor of the vehicle V and may be embodied in a wire harness 10 that electrically connects the high-voltage battery 12 and the inverter 11.

-   -   In the above-described embodiment, the inverter 11 and the         high-voltage battery 12 were adopted as the electric devices         connected by the wire harness 10, but there is no limitation to         this. For example, the present disclosure may be adopted in a         wire connecting the inverter 11 and the motor for driving the         wheels. That is, the present disclosure is applicable as long as         it electrically connects electric devices mounted in the vehicle         V.     -   As in the embodiment shown in the drawings, the opening terminal         end portion of the first outer cover member 40 may be separated         with a space from the opening terminal end portion of the second         outer cover member 50. The protective member 60 of the         embodiment shown in the drawings may be configured as a         continuous tubular body that couples the opening terminal end         portion of the first outer cover member 40 and the opening         terminal end portion of the second outer cover member 50 such         that the opening terminal end portion of the first outer cover         member 40 and the opening terminal end portion of the second         outer cover member 50 are spaced apart from each other by a gap         in the axial direction. The protective member 60 of the         illustrated embodiment may have a first tubular end portion         configured to be attached to the outer surface in the radial         direction of the opening terminal end portion of the first outer         cover member 40, a second tubular end portion configured to be         attached to the outer surface in the radial direction of the         opening terminal end portion of the second outer cover member         50, and a tubular intermediate portion that extends between the         first tubular end portion and the second tubular end portion. In         one example, the tubular intermediate portion may be configured         such that the gap in the axial direction formed between the         opening terminal end portion of the first outer cover member 40         and the opening terminal end portion of the second outer cover         member 50 is not exposed to the outside of the wire harness 10.         In the embodiment shown in the drawings, the tubular         intermediate portion of the protective member 60 may be         configured to cover the entirety of the electromagnetic wave         absorbing member 80 sandwiched between the opening terminal end         portion of the first outer cover member 40 and the opening         terminal end portion of the second outer cover member 50, and         the exposed portion of the braided member 110 that is not         covered by the first outer cover member 40 and the second outer         cover member 50.     -   The positioning member 90 of the embodiment may be configured to         be coupled to the opening end portion of one of the first outer         cover member 40 and the second outer cover member 50 (e.g., the         first outer cover member 40) by engagement between a recess and         a protrusion, and may be configured not to be in contact with or         engaged with the opening end portion of the other of the first         outer cover member 40 and the second outer cover member 50         (e.g., the second outer cover member 50).     -   The electromagnetic wave absorbing member 80 of the embodiment         is referred to as an electromagnetic noise filter in some cases.         The positioning member 90 of the embodiment may function as an         electromagnetic noise filter anchor element configured to         position the electromagnetic wave absorbing member 80 to the         opening end portion of one of the first cover member 40 and the         second cover member 50 (e.g., the first cover member 40) in the         length direction and the radial direction of the wire harness         10.     -   The fitting portion 92 of the positioning member 90 of the         embodiment can have a first state in which the fitting portion         92 is not inserted in the opening end portion of one of the         first outer cover member 40 and the second outer cover member 50         (e.g., the first outer cover member 40), a second state that is         after when the fitting portion 92 is inserted into the opening         end portion of the one outer cover member (e.g., the first outer         cover member 40), and immediately before when the projecting         portion 96 is engaged with the one outer cover member (e.g., the         first outer cover member 40) through engagement between a recess         and a protrusion, and a third state in which the projecting         portion 96 is engaged with the one outer cover member (e.g., the         first outer cover member 40) through engagement between a recess         and a protrusion. The fitting portion 92 may have a first         curvature radius when the fitting portion 92 is in the first         state, and the fitting portion 92 may have a second curvature         radius that is smaller than the first curvature radius when the         fitting portion 92 is in the second state. When the fitting         portion 92 is in the third state, the fitting portion 92 may         have a third curvature radius that is larger than the second         curvature radius. The third curvature radius of the fitting         portion 92 may be the same as the first curvature radius or         smaller than the first curvature radius. When the fitting         portion 92 is in the third state, the outward-facing surface in         the radial direction of the fitting portion 92 may be in direct         contact with the inward-facing surface in the radial direction         of the one outer cover member.     -   In the embodiment, when the fixing member 100 is wound around         the outer surface of the fixing portion 94 covering the first         portion of the outer surface of the wires 20 and a second         portion that excludes the first portion of the outer surface of         the wires 20 and is not covered by the fixing portion 94, the         inward-facing surface in the radial direction of the fixing         portion 94 may press the outward-facing surface in the radial         direction of the wires 20.     -   The embodiments disclosed herein are to be considered exemplary         in all respects and not restrictive. The scope of the present         disclosure is indicated by the scope of claims, not the         above-mentioned meaning, and is intended to encompass all         modifications within the meaning and range of equivalency to the         scope of claims
